"D" cell battery gets hot
As a hobbyist, I was playing around with an MP3 player that uses a single alkaline AAA battery. I wanted to see if the player would still work if I attached a "D" cell battery to the device. I went to Radio Shack and puchased a "D" cell battery holder which has two leads.
I added connectors on the end of each lead and plugged them into the player. The player worked properly.
I then disconnected the leads from the player and left the "D" cell battery in the holder sitting on the table. It sat for about an hour and when I went to remove the battery, it was HOT to the touch. The two leads were not connected to anything or laying against anything.
I am truly puzzled as to why the battery got hot. I thought if nothing was attached to the
leads, it was not completing a circuit. So why did the battery get hot?
I figured this is a great site to pose this question.
Thanks in Advance
